pnmtofits - convert a portable anymap into FITS format
pnmtofits
[-max f] [-min f] [pnmfile]
Reads a portable anymap as input. Produces
a FITS (Flexible Image Transport System) file as output. The resolution
of the output file is either 8 bits/pixel, or 16 bits/pixel, depending
on the value of maxval in the input file. If the input file is a portable
bitmap or a portable graymap, the output file consists of a single plane
image (NAXIS = 2). If instead the input file is a portable pixmap, the output
file will consist of a three-plane image (NAXIS = 3, NAXIS3 = 3). A full
description of the FITS format can be found in Astronomy & Astrophysics
Supplement Series 44 (1981), page 363.
Flags -min and -max can be
used to set DATAMAX, DATAMIN, BSCALE and BZERO in the FITS header, but
do not cause the data to be rescaled.
